Anyways, for your balrog, I see two possibilities. One is that it might be 'stuck' on top of some orcs. There are monster teleporters in the main room and creatures can form stacks there. The other option is that he might have wandered into the tomb of Balin. Getting there and driving him out without dying from repeated balrog hits might be a challenge. I know I hated it when it happened to me. Especially since the infinite ork problem is not fixed in the version I play.
And Inanity, yes. As far I can tell, solving "Strong Quick and Rich" is the only way out of this area. And yes, you ended up there by falling down a pit, you clumsy, clumsy you!
